Sony A390 vs Sony TX1: An In-Depth Comparative Review for Enthusiasts and Professionals

When evaluating cameras within Sony’s diverse lineup, it is essential to understand how model categories and design philosophies distinctly shape the user experience and photographic outcomes. The Sony Alpha DSLR-A390 (A390) and the Sony Cyber-shot DSC-TX1 (TX1) represent two very different approaches: the A390 as an entry-level DSLR aimed at enthusiasts seeking classic manual control and lens versatility, and the TX1 as an ultracompact fixed-lens camera designed for portability and ease of use. Through meticulous hands-on testing across multiple photographic disciplines, technical breakdowns of imaging systems, and practical usability assessments, this article delivers a comprehensive comparison to help photographers - whether beginner or professional - make informed purchasing decisions aligned with their creative demands and budget considerations.

Physical Design & Ergonomics: DSLR Bulk Versus Ultracompact Convenience

Physically, the Sony A390 and TX1 could not be more different. The A390 is a compact DSLR, measuring 128x97x86mm and weighing 549g, clearly designed to offer robust handling and accommodate a wide range of interchangeable Sony/Minolta Alpha-mount lenses (143 compatible lenses at launch), suited for photographers seeking creative versatility. In contrast, the TX1 ultracompact measures a mere 94x58x17mm, weighing only 142g, emphasizing pocketability and convenience without interchangeable lenses.

Handling and Controls

The A390 adopts a traditional DSLR grip and control layout, allowing intuitive access to shooting modes including shutter priority, aperture priority, and full manual exposure - a must for learning and mastering photography fundamentals. While its controls are somewhat dated by modern standards, the body includes a tilting 2.7" screen and an optical pentamirror viewfinder with 95% coverage and 0.49x magnification, reinforcing classic DSLR shooting habits. The A390’s physical buttons and dials, though not illuminated, provide tactile feedback facilitating operation even in dim environments.

In comparison, the TX1’s fixed-lens design sacrifices operational complexity for a streamlined touchscreen interface on a 3" fixed LCD panel. The touchscreen supports live view framing and simplifies focus/framing adjustments but lacks manual exposure controls completely - a clear disadvantage if fine creative control is required. Without a viewfinder, reliance on the LCD can challenge bright outdoor shooting but suits casual snapshots and travel photography where rapid deployment outweighs precision.

Control Layout and User Interface: Traditional DSLR Versus Minimalist Compact

Assessing the top-view control layouts reveals how each camera prioritizes user input modalities. The A390 positions its mode dial, exposure compensation, and dedicated function buttons prominently, supporting fast changes to aperture, shutter speed, and ISO without diving deep into menus. Nikon’s contemporaries showed stronger ergonomics, but Sony’s inclusion of custom white balance, multiple metering modes, and straightforward exposure compensation adjustments, combined with live view AF, positions the A390 as a well-rounded entry-level DSLR.

The TX1 omits traditional mode dials, relying heavily on its touchscreen interface to switch modes and settings. While this design reduces external clutter, it imposes limitations for users desiring immediate access to manual or semi-automatic modes, which are absent altogether. The lack of physical exposure compensation or shutter/aperture controls restricts its appeal primarily to point-and-shoot enthusiasts prioritizing portability.

Sensor Technology & Image Quality: APS-C CCD Against 1/2.4" BSI-CMOS

Central to any camera evaluation is sensor performance, directly influencing image resolution, dynamic range, and low-light capabilities.

Sensor Specifications

• Sony A390: Utilizes a 14.2MP APS-C sized CCD sensor (23.5 x 15.7mm), a relatively large 368.95 mm² sensor area by compact cam standards. Despite moving through the legacy CCD path, its sensor integrates Sony’s Bionz image processor to produce RAW-capable, high-resolution files at 4592x3056 pixels, supporting 3:2 and 16:9 aspect ratios with a native ISO range of 100 to 3200. The sensor incorporates an anti-aliasing filter to control moiré, trading some micro-detail for cleaner images.

• Sony TX1: Features a 10MP 1/2.4" BSI-CMOS sensor (6.1 x 4.6mm), significantly smaller at approximately 27.94 mm² sensor area. Its backside illumination enhances light collection efficiency, compensating partially for sensor size constraints, but it produces lower resolution images at 3648x2736 pixels. The native ISO range begins at 125 and also maxes out at 3200, although noise performance at higher ISO is challenged by smaller sensor dimensions.

Real World Image Quality

Testing reveals that the larger APS-C CCD of the A390 attains markedly superior image quality in almost all parameters. Color depth and dynamic range - measured by DXO Mark scores of 22.5 bits and 11.5 EV respectively - enable rich tonal gradation and highlight retention especially beneficial in landscape and portraiture. Noise levels remain more controlled up to ISO 800, while the sensor’s low-light threshold supports usable imagery at ISO 1600 and 3200 with acceptable grain, aided by sensor-shift stabilization.

Conversely, the TX1 delivers respectable output for everyday snapshots, benefiting from BSI sensor sensitivity but constrained by sensor size - resulting in noticeably more noise in shadows and highlights losing detail under challenging lighting. The smaller sensor also limits depth of field control and overall dynamic range, which can be restrictive for advanced applications like landscape or fine-art photography.

Viewing and Interface: Optical Viewfinder Versus Touchscreen LCD

The A390’s optical pentamirror viewfinder edges out the TX1’s lack of viewfinder by offering a near-real-time, zero-lag framing solution, though its 95% coverage means occasional recomposition may be needed. The tilting 2.7" 230k-dot LCD supplements composition options and live view shooting, essential when using live view autofocus or reviewing images.

In contrast, the TX1 replaces viewfinder use with a larger 3" 230k-dot fixed TFT LCD touchscreen enabling intuitive focus and shooting parameter adjustments. While convenient for casual photographers, the screen’s reflectiveness and lack of tilt limit usability in bright outdoor settings or at awkward angles, and absence of an EVF forces users to rely wholly on the LCD for framing and reviewing.

Autofocus Systems: Nine-Point Phase Detection vs. Contrast Detection

The A390 employs a 9-point phase-detection autofocus system inherited from Sony’s Alpha DSLRs, including face detection in live view mode, and supports autofocus continuous servo mode for tracking moving subjects, albeit limited by entry-level speed. This setup caters well to portrait and action photography where decisive focusing is essential.

Meanwhile, the TX1 features a contrast-detection AF system with 9 focus points but lacks face detection or tracking capabilities. This AF system is optimized for general scene recognition but struggles in low-contrast or low-light situations and cannot continuously track motion effectively. It suffices for static subjects and casual snapshots but does not accommodate sports or wildlife demands.
